Hello there
I have a ls1 in a 69 camaro and the turbo setup is completely blocking the heater core outlet ports ( there plugged flush ) im wondering where can i tap or get a supply and return to my vintage air heater setup ?

I have seen posts where people plug the existing ports then drill and tap the ports straight down from above. A more traditional way is to tap the existing ports (1/2 and 3/8 npt) and use 90° AN fittings.

Try a search.

Nice thing about aluminum water pumps if you screw something up you can use a TIG welder like an eraser.

get some aluminum an fittings and weld them on...and use a "T" and you should be good to go

I tapped mine and used 90 degree fittings. Others have plugged the inlet/outlet and drilled and tapped just above the old fittings.
I think the new LS9 water pump is done that way too.

Thanks for the tips but like i said i have a turbo covering the ports there might be about 1/8" gap between water pump and turbo as i never planned on running a heater until i got the vintage air setup. But i like the idea of drilling under the ports and running fittings straight down !
